Noted 👍

You’d be surprised when you look at pvc enclosure how little people selling those seem to take for themselves, but I understand.

Maybe. Mine are on the floor and basically front opening and I don’t have a problem but a top opening could work as well. You could just ask someone to build a box of the desired dimensions without the top + a frame to attached the lights + a top that would just rest on the light frame. Note that the lights would always stay in place and the cleaning could maybe be a little annoying at time because of them.
I guess i am going to make the joiner make half of the top or a little bit less and the rest i am going to tell him to make it as a door but only frame so i can add a piece of glass acrylic

Is this fixture good
if i added the substrate 15cm deep and the height was 80cm there should be 54cm between the substrate and the heat lamp
I’m no expert but if this is for the basking area or a CHE you’d want something with a reflector around 10in wide. Most people use reptile specific domes or brooder lamps.

I don’t know what dimensions you have in mind but that could make things difficult to clean really fast since half the enclosure would be very difficult to reach. You could ask them to make two door of half the enclosure each if you’re worried about weight

Yes a dome will be needed.
Can i just make an open top enclosure and add a box on top of it upside down to get the extra height as needed for example if I don’t need extra height i will just add a top and if i need 15cm i will add a 15cm height box
id just make it so the overall think measures around 2ft in height(should be enough wiggle room for bulb heights) if you go with something like the idea I posted above, it could work, but I would try having a shop around personally, as mentioned above you’d be surprised what you can get second hand!

Is 100w overpowered if the distance between the SUBSTRATE and the lamp is around 54cm?

I need to find a dome fixture that can be attached to the top with screws and not hanging up because if it’s hanging it would be really close to the tortoise and if i increase the height the UVB would be really away

Only your thermometer will be able to determine if the watt is overkill, this is when you may need to play around with the height a bit, sometimes folks have to get multiple watts to see which is best.

You can still hang it so it’s near the top, but just to check, you aren’t getting an all in one uvb and heat bulb? You need a floodlight and t5 uvb separately so you can adjust the height of either. Here’s an example of how to hang the dome from the ceiling, most come with that metal hanging bit

If you were to do that you would never be able to provide your tortoise a 95-100f basking area. 60-80cm is enough for a dome, I have one with a 75w floodlight and it works great. I can adapt the height for my tortoises to have the perfect temperature. What you need is a dome and a way to secure it to the top while keeping the option to lower it. You want a dome because it helps direct the light towards the ground and it allows the light to heat a wider area, this is much more efficient.

Of course not getting an all in one UVB and heat bulb

You mean the whole enclosure height or the height between the substrate and the dome?

Let’s say you decide to have a 80cm high enclosure. You could add a hook to the top (like @Littleredfootbigredheart just showed you) then you would attached your dome to it (the fixture would come done to maybe 65cm min), put a floodlight in, then use a thermometer to get the temp at substrate level. If the temp is too high get a lower wattage floodlight, if it’s too low use chains to lower the dome towards the substrate until your basking area is 95-100f.

The problem is that I can’t find a 10 inch wide dome fixture only found 5.5 inch(wide) deep dome which will make the fixture come down to 50cm min

Try to find 8in maybe, if not 5.5 would probably be fine, it’s not optimal but if you can’t find bigger it will have to do.
30cm deep for a dome seems weird though, you’d want something less deep.
Can you post a picture?

Try to find something wider and/or less deep (focus specifically on wider) but if you can’t this will work better than no reflector at all.

Our enclosure has an overall height of 2ft, I’d go 2.5ft at absolute most personally, that’s for the overall height of the enclosure floor to ceiling.
Yeah I’d try having a look for another dome if you can, try typing in 10inche brooder dome, you want one with a ceramic fitting👍

They are babies (3-4 months age)
How can i make the ventilation?
You don't need ventilation. You need warm temps and humidity. Ventilation will take all that away. The enclosure will not be air tight. There will be gaps all around the doors and other places. If you want ventilation, you can drill some holes, but be prepared to caver the holes with tape if you start losing all your heat and humidity.

Should i put the pond liner under the substrate only or all over the enclosure

Logic answer -

1. Babies need high humidity.

2. The best way to have consistent heat and humidity is to have a closed chamber with the bottom couple inches of substrate wet enough for the moisture to evaporate up through the rest of the substrate and chamber.

3. If your substrate is that wet AND you have the pond-liner only under part of it, since water seeks the lowest level, the water will go all over the place including under the liner, and there would be no reason to have a liner in there at all.

I meant the pond liner should cover the base and walls or the base only

Think about it. That was already answered in the post above.

What is the reason you are putting a liner in?

How do the physics of gravity and water work?

Where does that tell you to put the liner?
